Study summary

The goal of this clinical trial is to learn if topical netarsudil/latanoprost works to treat pseudophakic bullous keratopathy in patients with glaucoma. The main questions it aims to answer are:

Does topical netarsudil/latanoprost improves visual function in patients with glaucoma and pseudophakic bullous keratopathy? Does topical netarsudil/latanoprost affects the central corneal thickness (CCT) in patients with glaucoma and pseudophakic bullous keratopathy? Researchers will compare topical netarsudil/latanoprost to a placebo (a look-alike substance that contains no drug) to see if topical netarsudil/latanoprost works to treat pseudophakic bullous keratopathy (PBK).

Participants will take topical netarsudil/latanoprost or a placebo every day for 12 weeks and visit the clinic once every two weeks for checkups and tests.

Read the detailed description

Patients with glaucoma and pseudophakic bullous keratopathy will be randomly divided in two groups. Group 1 will take topical netarsudil/latanoprost 1x daily for 3 months and group 2 will take topical placebo (artificial tear substitute) 1x daily for 3 months. Visual acuity (VA) will be evaluated using Snellen chart and converted to logarithm of the minimum angle of resolution (LogMAR). Central corneal thickness (CCT) measurements will be performed using OCT (Optovue Ivue). Information about intraocular pressure and adverse effects will be recorded during the study. Patients will visit every two weeks for checkups and measurements for 12 weeks.
